SANITARY TRAY.

Specification of Letters Patent.

Patented May 22, 1917.

Application filed October 31, 1916. Serial No. 128,768.

the tray in a horizontal position with re-- spect to the supports.

Another object of the invention is to provide novel means for assemblingwith the tray supports, a pair of side strips between which the trayfits.

The invention aims, generally, to provide a. high chair tray which canbe cleaned out readily.

It is within the province of the disclosure to improve generally and toenhance the utility of devices ofthat type to which the 1 presentinvention appertams.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides inthe combination andarrangement of parts and in the details of construction herelnafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawing Figure 1 shows in perspective, a portion ofa high chair equipped with the device forming the subject-matter of thisapplication' Fig. 2 is a transverse section taken through the tray fromthe back of the tray toward the front of the tray, parts of the chairproper appearing in elevation;

Fig. 3 is a vertical section taken approxi-- mately on the line 3-3 ofFig. 1;

Fig. 4 is a fragmental top plan of the tray and attendant parts,portions being broken away, the view depicting a slight modification inthe invention.

In Figs. 1 and 2 of the drawings there 1s shown a part of a high chairincluding a back 1 having arms 2. Supports 3 are shown, the same beingpivoted at 4 to the back 1. Intermediate their ends, the supports 3 areconnected by a rod 5 having nuts 6 or the like at its ends, the nutsengaging the outer faces of the supports 3. The rod 5 prevents thesupports 3 from spreading apart.

The numeral 7 designates, generally, a tray In Fig. 2, the tray is Shownas comprislng a bottom 8, a front bar 9 secured to the bottom, and arear bar 10 secured to the bottom. There is nothing to prevent the traybeing manufactured in one piece, if desired. The bars 9 and 10 upstandabove the'bottom 8 of the tray, and the tray, therefore, maybe describedas being in the form of a trough which is open at its ends. In the rearface of the bar 10 there is formed a recess 11 extended from one end ofthe bar to the other end and defining a shoulder 12. Mounted .in thesupports 3 near to their outer ends, are pivot elements ll of anydesired sort. The pivot elements 14 enter the ends of the front bar 9 ofthe tray 7, and thus the tray is mounted for vertical swinging movement.The shoulder 12 rests on the rod 5, and thus the tray is held in ahorizontal position between the supports 3.

Applied to the inner faces of the supports 3 are side strips 15 whichpreferably are made of metal. The side'strips 15 have beads 16 at theirupper edges, which overhang and engage the upper edges of the supports3. The rod 5'passes through the rear ends of the side strips 15, and thepivot elements 14 pass through the forward ends of the strips 15. Inthis manner, the strips 15 are held on the supports 3. The side strips15 lie at the end of the troughshaped tray 7 and constitute closures forthe ends of the tray.

The tray 7 may be swung upwardly and forwardly, and thus material whichhas accumulated within the tray may be dumped out, or the material maybe wiped out through the ends of the tray, when the tray rises above theside strips 15. The side strips 15 serve to prevent the supports 3 frombeing marred by the ends of the tray 7, when the tray 7 is swungupwardly and downwardly. The rod 5 acts not only as a stop for holdingthe tray 7 in a horizontal position, but serves, also, to prevent thesupports 3 from spreading apart. When the tray 7 is in a loweredposition, the tray rests on the arms 2. The nuts 6 may be tightened upso that the supports 3 bind the strips 15 against the ends of the tray 7In this manner, tight joints are afforded, and, at the same time, thetray 7 is prevented from swinging upwardly on the pivot elements 14.when the tray rests on the arms 2, as shown in Fig. 2.

It will be understood that beads 16 on the side strips 15 may beconstructed as desired, depending upon the nature of the finish whichthe strips 15 are to have at their upper edges.

In Fig. 4: of the drawings, wherein a slight modification in theinvention appears, parts hereinbefore described have been designated bynumerals formerly used, with the suffix a. In this form of theinvention, the pivot elements 14 engage the rear bar 10 of the tray 7*,whereas the front bar 9 has a shoulder l2 which engages the rod 5, thelatter being mounted in the forward ends of the supports 8 Essentially,the difference between that form of the invention shown in Fig. 4, andthe form shown in Fig. 2, is that, in Fig. 2, the tray is mounted toswing forwardly, whereas in Fig. 4, the traIy swings rearwardly.

aving thus described the invention, what is claimed is 1. In a device ofthe class described, supports; a tray disposed between the supports andin the form of a trough which is open at its ends, the supportsconstituting closures for the ends of the tray; means for pivoting thetray adjacent one of its edges to the supports; and stop means coactingwith the tray to hold the same between the supports, whereby thesupports will constitute closures for the ends of the tray.

2. In a device of the class described, supports; a tray disposed betweenthe supports and in the form of a trough which is open at its ends, thesupports constituting closures for the ends of the tray; means forpivoting the tray adjacent one of its edges to the supports; and a rodconnecting the supports, the opposite edge of the tray resting on therod.

8. In a device of the class described, supports; a tray disposed betweenthe supports; means for pivoting the tray adjacent one of its edges tothe supports; a rod connecting the supports, the opposite edge of thetray resting on the rod; and a tightening device on the rod and engagingone support, to cause the supports to bind against the ends of the tray.

4. In a device of the class described, supports; a tray disposed betweenthe supports; pivot elements connecting the tray adjacent one of itsedges with the supports; a rod connecting the supports and coacting withthe opposite edge of the tray to uphold the tray; and side stripsinterposed between the supports and the ends of the tray, the sidestrips being carried by the pivot elements and the rod.

5. In a device of the class described, supports; a tray disposed betweenthe supports; pivot means connecting the forward portion of the traywith the supports; stop means carried by the supports and engaging thetray adjacent its rear edge; and side strips interposed between thesupports and the ends of the tray, the side strips being carried by thepivot means and the stop means.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
